Electro group Perfume has found another hit with their third album, “Triangle.” The album sold nearly 211,000 copies to take #1 on the weekly charts, giving them their second consecutive chart-topper after last year’s “GAME.” This also gives them the current 2009 record for first-week sales by a female group.

Miliyah Kato’s “Ring” achieved #2 with a strong showing of its own, at 151,000 copies sold. Also in the top ten were a “Mobile Suit Gundam 00” soundtrack (#5), TUBE (#7), the soundtrack to the latest “Evangelion” movie (#8), and MONGOL800 (#9).

On the singles chart, Tegomass claimed the top spot with their 4th single, “Tanabata Matsuri,” at 80,000 in sales. This was enough to earn them their second consecutive (third overall) number-one song. They outperformed even Kumi Koda, who settled for second place with her “3 SPLASH.”

Actor Ryuta Sato (29) has just revealed that he is soon to be a father. His agency had announced on Monday that he is engaged, and during his press conference on Tuesday, Sato personally shared the happy news of his coming child.

Wearing a black jacket for the conference, Sato said that his fiancee is expected to give birth around this fall/winter. He explained that he was initially planning to propose on May 30, the opening day of the “ROOKIES” movie. But sometime before that, his girlfriend surprised him with the news that she was pregnant, so he decided to propose that same day.

Sato’s wife-to-be is a 23-year-old who is said to have briefly been in show business. The pair have been dating since the end of 2005. Their wedding day has not yet been determined, though they plan to hold their ceremony after the child is born.

J-pop princess Koda Kumi (26) is finally going to show fans outside Japan what she’s made of. The Avex label announced yesterday that she will perform two concerts in Taipei on October 3-4. Koda has been one of Japan’s best selling artists of the last few years and has a growing fan base across East Asia. Though she made her international debut with a U.S. release as long ago as 2000, and has made appearances there and in Korea, the Taipei shows will be her first overseas concerts. She finished a Japan tour, with a show that cost about ¥80 million, in mid-June. Her latest single, “3 Splash,” has sold over 150,000 CDs and more than 300,000 downloads since it was released Wednesday.
